ROUTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 366,329, dated July 12, 1887.

Application filed April 12, 1886. Serial No. 198,5'26. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE E. LLOYD, of Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Engravel-s Routing-Machines, which have not been patented to me in any country; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompany ing drawings, and to the letters of reference marked thereon, which form a part of this specification.

According to the old method of transmitting power to routing-machines it is necessary to journal the heel of a vertical shaft in the corner of the bed of the machine where the oscillating sweep is journaled, and to impart the motion thereof by means of pulleys and belts, first to thepivotal point of the arm in which is journaled the spindle carrying the cutter and from thence to said spindle. This construction requires the use of bearings and hangers for the topof the vertical shaft, together with suitable gearing or means for communicating the motion of the main shaft thereto, and requires very nice adjustment of the machine with reference to the location of the means for connecting the main shaft and vertical shaft.

It is the object of my invention to do away with the vertical shaft and contingent devices and to impart the motion of the main shaft directly to thepulley located at the point of oscillation of the spindle-carrying arm and from thence to the spindle. This I am enabled to do by means of guide-pulley placed between the fulcrum of the sweep and the pivot of the spindle-arm, substantially as hereinafter described, and as illustrated in the drawings, in which Figure 1 is a perspective view of a routingmachine, showing the application of my invention. Fig. 2 is a front view, and Fig. 3 a side elevation, of my invention.

In the drawings, A represents the bed of a routing-machine.

13 represents the pivotal post, located preferably at one corner of the bed.

0 is the main sweep fulcrumed on said vertical post B, and has its outer end supported by a suitable frame, a.

D is an oscillating arm pivoted toa suitable sleeve or boss, which can be adjusted longit-udinally on said sweep O.

In the end of arm D isjournaled the verti cal spindle 'b, which carries the cutter in its lower end and has a pulley on or near its upper end ,which is connected by a belt toaspeed- 6 pulley journaled on the upper end of the pivotal pin of said arm. From the end of arm D extends a handle, which rests upon a suitable raised frame, (1, secured to that side of the bed which runs in the same direction as the sweep.

The machine as thus briefly described is the same as the old machine mentioned, and I lay no claim to it.

Connecting the pulley 6 with the main shaft is a belt, E, which travels horizontally and parallel to the sweep O to and around pulleys F F, and then vertically'to the pulley on the main shaft. These pulleys F are looselyjournaled side by side on the same spindle,which latter is secured in the arms of the bracket G. Bracket G is provided with a boss, which, by means of set-screws, can be adjusted longitudinally on said sweep anywhere between the fulcrum of said sweep and the pivotal point of arm D. I prefer, however, to locate it as near the fulcrum as possible.

The axis of the pulleys F may be exactly horizontal and at right angles to the length of the sweep; but I prefer to incline the said axis a little to the side away from the ma chine. If the lower end of the axis was slightly in advance of the other, it would enable the belt to travel better.

If desired, the bracket might be adjusted 0 on the sweep so as to be capable of lateral oscillation.

I do not wish to be confined to a bracket, as shown, for any device which would afford a journal for pulleys F, so that they would move with the sweep, or inthe same direction either zit its pivotal center or on its length, would said spindle is journaled, pulley e, and sweep answer. O, of pulleys F, belt E, and bracket G, adjust- What Iclaim as new, and desire to secure by able on said sweep.

Letters Patent, is GEORGE E. LLOYD. I
